Patent number: 9946482Abstract: A method for expanding a data memory for a microprocessor architecture which uses a bank select accessing scheme for accessing data memory which is divided into a plurality of memory banks. A bank select register is configured to select a memory bank and the microprocessor architecture has an instruction set with a dedicated instruction for selecting a memory bank. An opcode of the dedicated bank select instruction provides for a maximum of n bits payload thereby providing for an address value which is configured to select a maximum of 2n memory banks. The method has the steps of: using an opcode of a test instruction that provides for m bits of payload for a new bank select instruction, wherein m>n; and using an opcode of the dedicated bank select instruction for a new test instruction.Type: GrantFiled: July 13, 2016Date of Patent: April 17, 2018Assignee: MICROCHIP TECHNOLOGY INCORPORATEDInventors: Kevin Kilzer, Joseph Julicher, Jacobus Albertus Van Eeden

Patent number: 9823280Abstract: External conditions, e.g., smoke, temperature, humidity, humidity, pressure, flow rate, etc., affects a sensor's characteristics, wherein the sensor provides a current output representative of its characteristics as affected by the external conditions. The current output of the sensor is coupled to a sample and hold capacitor for a precision time period thereby charging the sample and hold capacitor to a voltage proportional to current provided by the sensor over the precision time period. The voltage on the sample and hold capacitor is converted to a digital representation and a determination is made whether the external condition represents an alarm situation, e.g., smoke detected from a fire.Type: GrantFiled: December 10, 2012Date of Patent: November 21, 2017Assignee: MICROCHIP TECHNOLOGY INCORPORATEDInventor: Joseph Julicher

Patent number: 9805572Abstract: An ion chamber provides a current representative of its characteristics as affected by external conditions, e.g., clean air or smoke. A direct current (DC) voltage is applied to the ion chamber at a first polarity and the resulting current through the ion chamber and parasitic leakage current is measured at the first polarity, then the DC voltage is applied to the ion chamber at a second polarity opposite the first polarity, and the resulting current through the ion chamber and parasitic leakage current is measured at the second polarity. Since substantially no current flows through the ion chamber at the second polarity, the common mode parasitic leakage current contribution may be removed from the total current measurement by subtracting the current measured at the second polarity from the current measured at the first polarity, resulting in just the current through the ion chamber.Type: GrantFiled: December 14, 2015Date of Patent: October 31, 2017Assignee: MICROCHIP TECHNOLOGY INCORPORATEDInventors: Joseph Julicher, Keith Curtis, Paul N.

Patent number: 9210769Abstract: A light emitting diode (LED) is driven with a plurality of pulses having controllable pulse widths and positions within clock time periods that provide for both LED light intensity control and digital information communications from a single output node of an integrated circuit (IC) device. The LED light intensity is determined by the duty cycle of the pulses where the human eye integrates these light pulses from the LED into continuous light intensity levels. The digital information contained in the light output from the LED is detected by a photo-detector that converts the light pulses into electric signals that are demodulated and read by a circuit debugger and/or manufacturing test station. The aforementioned operations allow continuous visual display and data transmission using only one output node of the IC device. This is especially advantageous when using low pin count IC devices.Type: GrantFiled: March 15, 2013Date of Patent: December 8, 2015Assignee: MICROCHIP TECHNOLOGY INCORPORATEDInventors: Joseph Julicher, Jerrold S.

Patent number: 9207209Abstract: A smoke detection sensor ion chamber has a leakage current that is dependent upon the permittivity of the ionized gas (air) in the chamber. Smoke from typical fires is mainly composed of unburned carbon that has diffused in the surrounding air and rises with the heat of the fire. The permittivity of the carbon particles is about 10 to 15 times the permittivity of clean air. The addition of the carbon particles into the air in the ion chamber changes the permittivity thereof that is large enough to detect by measuring a change in the leakage current of the ion chamber.Type: GrantFiled: November 2, 2012Date of Patent: December 8, 2015Assignee: MICROCHIP TECHNOLOGY INCORPORATEDInventors: Benjamin T.
